JOHN J. POWER, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE TOLEDO GLASS COMPANY, OF TOLEDO, OHIO,

A CORPORATION OF OHIO.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed April 10, 1900. Serial No. 12,279.

To all whom it may concern:

Be it known that I, JOHN J. POWER, a resident of'Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Making Glass Articles; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to apparatus for the manufacture of glassware, and has for its object to provide for the manufacture of hollow glass articlessuch as bottles, jars, tumblers, chimneys, and various other articles in hollow ware as well as articles of tubular or cylindrical form.

My invention consists, generally stated, in the novel arrangement, construction, and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use the apparatus, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a side view of the apparatus, showing the same as used in connection with a glass-pot. Fig. 2 is an enlarged longitudinal section of such apparatus for making bottles. Fig. 3 is a cross-section on the line 2 2, Fig. 2. Fig. 4 is a like view on the line X X, Fig. 2. Fig. 5 is an elevation of the neck and blank mold shown in Fig. 2 and looking at the opposite side of the same. and Fig. 6 is a sectional view of the neck and body or blow mold ready for the blowing operation.

Like numerals herein indicate like parts in each of the figures of the drawings.

As illustrated in the drawings, the apparatus is shown as used in connection with aglass-pot 1, located within the ordinary glass-furnace 2; but it will be obvious that the same can be used in connection with atank-furnace, if desired.

In this apparatus, 3 indicates the casing,

which is provided at one end with the screwthreads 3, adapted to engage with screwthreads 4, formed on flange 4 on the top of a partible neck-mold 5, the halves of which are hinged together by a pin 5 through lugs 5 on said mold 5 in the usual manner. The

neck-mold 5 is provided with the mold-cavity 6 therein, and each half of the mold 5 is provided with a tongue 6, adapted to slide and adapted to engage at their free ends with the side pieces 10 on the sides of the blank-mold 7, and so hold the halves of the mold 7 securely together. Extending down within the cavities 6 and 8 of the neck-mold 5 and blank-mold 7 is the core 11, which has a hollow portion 11 at its top and is provided with perforations 12 therein. The core 11 is also provided with a head 12 at its upper end, to which is secured the cylinder 13 by means of screw-threads 13, and working within the cylinder 13 is the piston 14, which is provided with the pistonhead 14: and piston-rod 15, having a handle 15 thereon for operating the same. Secured around the cylinder 13 and within the casing 3 is a frame 16, which consists of a ring16,

rigidly secured around the piston-rod 15 of the piston lei at the top of the casing 3 and cylinder 13, and a ring 17, which fits loosely around the exterior of the cylinder 13 within the casing3. Connected to and between the rings 16 and 17 are the supporting-rods 17, on one of which is formed the rack 18 for engaging with a pinion 19, which is secured to a pin or stud 19 on the inside of the casing 3, and this pinion 19 is also adapted to engage with a circular rack 20, secured around the exterior of the cylinder 13 for rotating said cylinder and the core 11.

- The operation of the above apparatus in the process of manufacturing bottles,or rather articles wherein the article is partially formed by a blowing operation, is as follows: The apparatus being ready, as shown in Fig. 1, the operator proceeds with the same to a pot 1 or tank-furnace, as desired, and inserting the mold 7 through the opening or mouth 1 of the pot or tank slightly submerges the open end -of the mold7 into the molten glass. The operator then draws back the piston 14 by means of the handle 15, thereby drawing the air out of the cavity 8 of the blank-mold 7 through the perforations 12 in the core 11, into the cylinder 13, thereby effecting a vacuum in the cavities 6 and 8 of the neck-mold 5 and blank-mold 7 and causing or permitting the molten glass to fill or How into the cavities 6 and 8 around the core 11, thus forming the finished neck and rim of the bottle or other article in the cavity 6 of the neck-mold 5 and a preliminary blank or hollow bulb of glass in the cavity. 8 of the blank-mold 7. When the operator thus draws back the piston 14, the frame 16, being rigidly attached to the piston-rod 15 by the ring 16, is also drawn back, thereby causing the rack 18 to operate the pinion 19, secured on the casing 8, which being in engagement with the circular rack 20, secured around the cylinder 13, will cause the cylinder, with its core 11 attached thereto, to revolve or rotate, and thereby prevent the molten glass from entering into the perforations 12. The apparatus is then withdrawn from the pot or tank 1, and the cylinder 13 is then drawn back suflicient to withdraw the core 11 from the glass in the cavities 6 and 8 of the neck-mold 5 and blank-mold 7, when the arms 10 can be raised away from the side pieces 10 on the blank-mold 7, so that the halves of the mold 7 can be withdrawn from the glass blank by inserting mold-handles (not shown, but which are common) in the side pieces 10 and sliding the blank-mold 7 away from the neck-mold 5 and depending blank through the medium of the tongues 6 on the mold 5 and the grooves 7 on the mold 7. The neck-mold 5 is then placed on top of a body or blow mold 21, so that the depending bulb of glass is suspended within the body or blow mold 21 from the neck-mold 5, after which the body or blow mold 21 can be closed around the preliminary glass blank or depending bulb of glass and the casing 3 can be detached from the neck-mold 5, as shown in Fig. 6. Air is then applied through the top of the neck-mold 5 into'the depending bulb of glass in any wellknown mechanical way, thus blowing the depending bulb of glass or preliminary blank to finished form within the cavity 21 of' the blow-mold 21. The neck-mold 5 and body or blow mold 21 can then be opened by the usual mold-handles and the finished article removed. The revolvingor rotating of the core 11 and cylinder 13 may be dispensed with; but it is desirable under some conditions, and it is evident that several apparatus may be used, as well as several neck-molds, blank-molds, and body or blow molds. It is also evident that the body-molds may be arranged and the blowing operation performed on either a stationary or rotary table, as desired, and it will also be evident that instead of blowing the blank to finished form by air-pressure it may be developed to such finished form by a vacuum being created in the blow-mold 21.

Itwillthus beseenthatmyimprovedapparatus for manufacturing glassware is cheap and simple in its construction and does not require the employment of any skilled labor.

Various modifications and changes in the various parts of the apparatus may be resorted to without departing from the spirit of the,

invention or sacrificing any of its advantages.
